Percutaneous endoscopic lumbar discectomy
두 가지 방법이 사용됐는데 1. near-migrated discs를 위한 수술방법으로 경사진 칼집이 disc space를 건너서 epidural까지 놓여지는것이다. 2.Epiduoscopic technique.는 far-migrated disc를 위한 수술로 칼집이 완전히 epidural 공간으로 부터 disc 공간으로 놓여지는것이다.
2. 환자의 특성(나이, 성별, 병변의 위치, 병변의 타입)
73명의 남자와 43명의 여자. 평균나이는 35.5세(18~65). 평균 follow up 기간은 14.5(9~20)달이다.
L4-5(65 cases, 56.0%) L5-S1 (47 cases, 40.5%), L3-4 (3 cases, 2.6%), and L2-3 (1 case, 0.9%).
3. 수술성과의 판정 방법(판정에 사용한 도구, 평가 점수)
Modified Macnab criteria; satisfactory (excellent or good) results were distributed as follows: 91.6% (98/107) in the down-migrated discs; 88.9% (8/9) in the up-migrated discs; 97.4% (76/78) in the near-migrated discs; and 78.9% (30/38) in the far-migrated discs (Table 2). The difference between near-migrated group (97.4%) and far-migrated group (78.9%) was statistically significant (P = 0.002), while the difference between down-migrated group (91.6%) and up-migrated group (88.9%) was not statistically significant (P = 0.569). The preoperative mean VAS of leg pain : 7.5 ± 1.7 (range 5–9), which significantly decreased to 2.6 ± 1.8 (range 0–3) at the final follow-up (P < 0.0001). The average return to work period : 14 days (range 1–48 days).
